Subject: [PATCH] tuna: Adapt show_threads cgroup output to terminal size
Passing the --cgroup flag to the show_threads command currently displays
long cgroup strings on the thread output and decreases readability.
Adapt the show_threads output to account for output string and terminal
size, and format output accordingly to improve readability. Add
--spaced flag to show_threads to print cgroups with spacing in
between thread outputs.

From 87f6d9e29bab615b03b26210e3ead493fd08fe1f Mon Sep 17 00:00:00 2001
From: Leah Leshchinsky <lleshchi@redhat.com>

Subject: [PATCH 3/6] tuna: Add --sockets command line option
The getopt version of tuna implements the --sockets argument which is used
to specify a cpulist from the cpu sockets on a system. The --sockets
and --cpus arguments in the getopt version override each other, such
that 'tuna -S 0 -c 1,2' will cause a cpu_list of [1, 2].
In the argparse cli, add support for a --sockets argument used to specify a
cpulist and is mutually exclusive with the --cpus and --nohz_full arguments.

From eba1333c50f8a5eebb12b523c30faffac33681b3 Mon Sep 17 00:00:00 2001
From: Leah Leshchinsky <lleshchi@redhat.com>
Date: Thu, 4 Aug 2022 09:39:10 -0400
Subject: [PATCH 1/6] tuna: Update command-line interface
The current command-line interface allows for chaining of multiple
actions, which results in ambiguous user input, a need for maintaining
variable states (thread-list, cpu-list, etc.) in the program, and a need
to type check input after parsing. The help menu can also be
overwhelming.
Allow for the use of argparse rather than getopt to significantly
simplify the program.
Provide subcommands and clearer usage menus for the user,
introduce type checking at the parser level, and remove
ambiguity for user input.

.SH USAGE EXAMPLES
If for instance the Ethernet NICs have multiple queues for both receive and transmit, each with its own IRQ, the Ethernet IRQs can be associated with a CPU socket:
.TP
-.B tuna -S 2 -i -q 'eth*' -x
+.B tuna isolate -S 2
+.TP
+.B tuna spread -q 'eth*' -S 2
Move everything off the CPUs in socket 2, then spread the IRQs for the Ethernet devices across those same CPUs.
